Why customers choose Cera Garden

Smart metal management for clear, vibrant water

Metal in fill water can cause staining and water that looks dull, even when the pool appears crystal clear. BioGuard Pool Magnet Plus is a concentrated chelating formula designed to bind iron, copper, and manganese, helping prevent metal-related staining and reducing color changes caused by metals. With regular use, you may notice water that shines and stains that don’t reappear as quickly after cleaning.

What it does

  • Effective Metal Stain Prevention: The chelating action wraps metals and helps deposit them in the filter for removal, supporting stain prevention and treatment of discolored water.
  • Protects Against Metal & Stains: Prevents new staining and can assist with fresh metal stains; also helps eliminate discolored water caused by metals.
  • Reformulated & More Concentrated: Now more concentrated and effective; monthly use is recommended for pools with iron-containing fill water, staying active for about 3–4 weeks.
  • Application & Dosing: Initial dose: 1 quart per 10,000 gallons. For high metal levels, pair with BioGuard Sparkle Up. Maintenance: 3 oz per 1,000 gallons of fill water added. Fresh stains: 1–3 quarts depending on severity.
  • Tested & Reliable: BioGuard products are known for delivering reliable results and simplifying pool care.

Real-world use and tips

Many pool owners add this as a monthly step—especially in areas with metal-rich fill water or after periods of heavy rainfall that can introduce metals. When used alongside Sparkle Up, the combination supports metal removal and water clarity.

Practical notes: Follow the established dose, monitor metal levels, and maintain your regular BioGuard routine. The product is designed to be easy to apply and fit into a typical pool-care regimen without complicated steps.

FAQ
